Insights
The Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA) found no survival benefit for statin therapy in patients with ischemic systolic heart failure (HF). This challenges previous retrospective findings on statins for HF prevention and treatment.
Area of Science:
- Cardiology
- Pharmacology
- Clinical Trials
Background:
- Post hoc analyses suggest statins benefit heart failure (HF) patients.
- Prospective data on statins for HF morbidity and survival were limited before 2007.
Purpose of the Study:
- To evaluate the impact of statin therapy on heart failure (HF) morbidity and survival.
- To critically assess recent literature on statins in HF, considering potential biases.
Main Methods:
- The Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA) was a large-scale prospective trial.
- The study focused on patients with ischemic systolic HF treated with low-dose rosuvastatin.
Main Results:
- The CORONA trial reported no survival benefit in patients with ischemic systolic HF receiving low-dose rosuvastatin.
- Existing retrospective data on statins for HF present uncertainties due to potential biases and lack of mechanistic data.
Conclusions:
- The CORONA trial results introduce uncertainty regarding statin efficacy in specific HF populations.
- Further investigation is needed to clarify the role of statins in heart failure management, addressing data limitations.
Abstract:
Despite many post hoc analyses of cardiovascular databases in recent years suggesting a benefit of statins in the prevention and treatment of congestive heart failure (HF), a prospective study of statin therapy on two clinically relevant end points--HF morbidity and survival--had not been reported until 2007. However, a large-scale prospective trial, Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA), has just reported its primary results. These results somewhat surprisingly show no survival benefit in a group of patients with ischemic systolic HF given low-dose rosuvastatin. In addition to this uncertainty generated by the results of CORONA, there remains additional uncertainty in the existing, predominantly retrospective data on statins because of the potential bias in study designs, use of post hoc subgroup analyses, and lack of mechanistic data. This review critically evaluates the recent literature in this area.
